Note, to replicate with a 1.0 CouchDB instance you must first upgrade in-place
your current CouchDB to 1.0 or 0.11.1 – backporting so that 0.10.x can
replicate to 1.0 wouldn’t be that hard. All that is required is patching the
replicator to use the application/json content type.

_log and _temp_views are now admin-only resources.

_bulk_docs now requires a valid Content-Type header of
application/json.

JSONP is disabled by default. An .ini option was added to selectively
enable it.

The key, startkey and endkey properties of the request object
passed to list and show functions now
contain JSON objects representing the URL encoded string values in the query
string. Previously, these properties contained strings which needed to be
converted to JSON before using.

Warning

Version 1.0.4 contains important security fixes. Previous 1.0.x
releases are not recommended for regular usage.
